Hello. I Have Been Infected With Salmonella Since January 1,

Hello. I have been infected with salmonella since January 1, 2018-first bowel and stomach-so severe I was hospitalized for 3 days -IV antibiotics and hydration -then I got C-Dif- that cleared up, but then salmonella infiltrated my urinary tract beginning of March-then my bladder and it is still there. I now self catheter-4 times a day-have been nauseated every day since onset, without relief. I am exhausted all of the time. None of my team of doctors have ever treated (or even seen) salmonella in the bladder. I live minutes from Boston, and with all of "the best medical universities and hospitals" I cannot find a doctor familiar with this salmonella who can cure me. Anyone familiar with this? I feel like I am going to die from it.
